ID help please

[Toof Monster]

I have no idea. Found in North Charleston, SC in a recently dug pond. Any ideas?

[Ludwigia]

Could it be part of a large ray plate?

[Toof Monster]

Any other ideas?

[ynot]

Looks like an odd concretion to Me.

[Darren Garrison]

Could it be a tooth fragment from a young mammoth? (Totally non-expert guess.)

[Darko]

Maybe its a tooth  fragment from the  baby mammoth?

 

[Sagebrush Steve]

Banded chert?

[fifbrindacier]

It more likely is a banded chert or a concretion.

[Toof Monster]

It's not a banded chert. It is definitely bone of some sort. It was found in a layer with a lot of marine fossils. 

[ynot]

I agree that it is not a banded chert, the texture is wrong for that.

I do not agree that it is bone, again the texture is not right.

It does have the texture that I would expect to see in a concretion. And being found in a layer where fossils are found does not exclude concretions as the two are often found together. The only other thing I can think of, that would look like this, is a piece of layered siltstone.

Sticky with the marine theme...Could it be a really beat up partial fish mouth part like Diodon has? I've got some pretty good sized ones and they have a similar banding.

Do Your pieces have a change in the banding like this?

[Plantguy]

My unpaid imaginary assistant is in the garage looking for examples right now. He's doing a lot of grumbling and mumbling and doesnt seem to understand the organization scheme or lack there of....Let me see if we can find something to rule this wild idea in as a possibility or rule it out...hes been asked for clear pictures--...LOL.

Ok, here's some photos. I can't decide but am leaning to nixing my fish mouth part possibility . Your specimen is quite worn and compared to the fish part examples I have it appears to have a different type of relief but similar alternating bands. While looking at some fish mouth part examples I noticed several turtle shell pieces and made a comparison--they do look similar too but I'm not convinced. First shot shows the common views of these mouth parts and the 2nd shot shows what the sides/cross section patterns look like.  

 

 

Lastly, the third shot is a turtle shell remnant that has some similarity as well.

Need Eric or some of the others who are more familiar marine scraps or can research this further to nail this one down for you. 

 

Regards, Chris .

Thanks Chris.

@Toof Monster

 

Can you take good in focus pictures of the sides (to see if there is bone texture) the bottom and again of the top. Please make sure the item is the center of attention in the picture. Preferably not in your hand. Also give up good dimensions; width, length (depth) and thickness. 

 

This item intrigues me, but I am not ready (or able) to make a guess on the ID at this time.

am in the very worn small mammoth tooth frag camp

South Carolina is not all that far from Florida (finds below)

Some similar:

The more I look at pictures, the more it looks like a worn baby mammoth tooth. Idk, new one for me...

[Sharks of SC]

I agree with phosphate nodule, I see a lot of these in the marine sites locally. Nice finds, by the way!
